Left Disc DRAGS...??????

My duster dose the same although I don't think the one side is draging so much as the two calipers are not the same. Stupid me when I got them I thought they would be a matching pair but one has a stainless piston and one has a phonolic piston and I have a feeling that the two have diffrent piston diameters which will couse one side to lock up before the other I'n my case the drivers side.
